Called also Sheer, Great and Holy and Green (Gründonnerstag) this day initiates the Easter Triduum, the commemoration of the passion, crucifixion and resurrection of Jesus and is derived from a corruption of the Latin term
mandatum for command—from the Vulgate of John 13:34, wherein the disciple relays that there is a new directive, namely, that we love one another as I have loved you (Mandatum novum do vobis ut diligatis invicem sicut dilexi vos) and whereupon Jesus demonstrates his humility and charity in washing the feet (
pedelavium) of students to show there is no hierarchy in kindness. This courtesy ablution is not only a religious rite in many traditions but moreover a mark of hospitality in guest-host dynamics.
